TCR Engineering Services provides a comprehensive range of metallurgical and mechanical testing services with a dedicated machine shop to provide specimen preparation. Test specimens are prepared for metallic and non-metallic materials in the evaluation of tensile, compression, impact, weldability, fatigue and bend properties.

TCR has in-house Mechanical Testing Facility to provide precise determination of Proof Stress by the attachment of various Electronic Extensometers. Tensile test at Elevated Temperature is a special service offered by TCR. Tests are conducted as per ASTM, BS, IS, DIN, NACE or client specified standards. Our Mechanical Testing Capabilities include:

• Tensile Testing
• Impact Test
• Weldability
• Bend Test
• Compression
• Flaring / Flattening
• Hardness Testing
• Nick Break
• Drop Weight
• Proof Load
• Fasteners
• Hydraulic / Pneumatic
• Component Testing, and more.

Routine testing of fasteners, chain materials, weld coupons, wire rope, castings, sheet, plate, forgings and other components is done in an expedient manner providing an efficient, quality conscious service.

Our customers can feel confident that not only routine but also the most diverse test requests will be handled by our highly experienced engineers and technicians. Our Mechanical Testing Laboratory includes:
